第一部分：核心语法点

宾语从句

这是本册的重点和难点,必须牢固掌握。

• 定义：在句子中作宾语的从句，它由一个引导词引导，跟在动词、介词或形容词后面。
• 引导词：
  • that：无实际意义，只起连接作用，在口语和非正式文体中常被省略。

    例：I think (that) he is right.

  • if / whether：意为“是否”，不充当句子成分，不能省略。
    • 例：I wonder if/whether it will rain tomorrow.
    • 注意：介词后面只能用 whether，不能用 if。
    • 例：It depends on whether we have enough time.
  • 特殊疑问词：who, what, which, when, where, why, how 等，它们在从句中充当相应的句子成分（主语、宾语、状语等）。
    • 例：Can you tell me what time it is? (what 作 time 的定语)
    • 例：I don't know why he is late. (why 作状语)
• 语序：无论主句的时态如何，宾语从句都必须使用陈述句语序（主语 + 谓语 + ...）。
  • 错误：Do you know where is he?
  • 正确：Do you know where he is?
• 时态：
  • 主句是现在时或将来时，从句可以根据需要使用任何时态。
    • 例：I know he was busy yesterday. (一般过去时)
    • 例：I know he is busy now. (一般现在时)
    • 例：I know he will be busy tomorrow. (一般将来时)
  • 主句是过去时，从句通常需要使用过去的某种时态（“主过从过”原则）。
    • 例：He said he was a student. (was 对应 is)
    • 例：He told me that he had finished his homework. (过去完成时)
  • 客观真理或事实，无论主句是什么时态，从句都用一般现在时。
    • 例：The teacher told us that the earth moves around the sun.

定语从句

这是本册的另一个语法重点,用来修饰名词或代词。

• 定义：在句子中作定语，修饰某一名词或代词的从句。
• 结构：被修饰的名词/代词 + 关系词 + 从句
• 关系词：
  • that: 指代人或物，在从句中作主语或宾语，作宾语时可省略。
    • 例：The book (that) I bought yesterday is very interesting. (that 指物，作 bought 的宾语，可省略)
    • 例：The person that is standing over there is my teacher. (that 指人，作主语，不可省略)
  • which: 指代物，在从句中作主语或宾语，作宾语时可省略。

    例：The story (which) you told me is funny. (which 指物，作 told 的宾语，可省略)

  • who: 指代人，在从句中作主语或宾语（作宾语时可省略，但较少见）。

    例：The boy who is playing basketball is my brother. (who 指人，作主语)

  • whom: 指代人，在从句中作宾语，在现代英语中常被 who 或 that 替代，或省略。

    例：The man (whom/who/that) I spoke to is our new boss.

  • whose: 指代人或物，表示“……的”，在从句中作定语。
    • 例：This is the boy whose father is a doctor. (whose 指男孩的)
    • 例：I live in the house whose window faces south. (whose 指房子的)
• 关系副词：
  • when: 指时间，在从句中作时间状语。

    例：I still remember the day when I first came to this school.

  • where: 指地点，在从句中作地点状语。

    例：This is the town where I was born.

  • why: 指原因，在从句中作原因状语，常与 reason 搭配。

    例：Do you know the reason why he was late?

被动语态

• 定义：主语是动作的承受者，而不是执行者。
• 结构：be + 动词的过去分词
• 时变化：
  • 一般现在时：am/is/are + done

    例：Homework is finished every day.

  • 一般过去时：was/were + done

    例：The book was written by Lu Xun.

  • 一般将来时：will be + done / am/is/are going to be + done

    例：A new school will be built next year.

  • 现在完成时：have/has been + done

    例：This work has been finished already.

  • 含有情态动词的被动语态：can/may/should + be + done

    例：The room must be cleaned right now.

• 用法：
  1. 不知道或没必要指出动作的执行者。
  2. 强调动作的承受者。
  3. 在科技、新闻、正式文体中使用广泛，显得客观。

情态动词

• can / could:
  • can: 能力，许可 (can't = can not)
  • could: can 的过去式，表示过去的能力；更委婉的请求或许可。
• may / might:
  • may: 许可，可能性 (may not)
  • might: may 的过去式，可能性比 may 更小。
• must / have to:
  • must: 必须，一定 (mustn't = must not，表示“禁止”)
  • have to: 不得不，强调客观需要。have to 有多种时态形式，must 只有现在时。
• should / ought to:
  • 应该,表示责任或建议。shouldn't 表示“不应该”。
• will / would:
  • will: 意愿，将来时助动词
  • would: will 的过去式；表示委婉的请求或意愿。

非谓语动词

  • 作宾语: want to do, decide to do, hope to do, agree to do 等。

2. 在语境中记单词: 不要死记硬背单词表，把单词放到课文、对话和例句中去理解和记忆，并尝试用它们造句。
3. 重视阅读和听力: 通过阅读不同题材的文章（如课本、新闻、简易读物）来巩固词汇和语法，培养语感，多听英语材料，提高听力理解能力。
4. 勤于练笔和开口: 尝试用英语写日记、小作文或回答问题，大胆开口说英语，可以自言自语，也可以和同学练习对话。
5. 整理错题本: 把做错的题，特别是语法题，记录下来，分析错误原因，定期复习，避免再犯。
